The U.S. Court of Appeals for the DC Circuit decided the case of Allegheny Defense Project, et al. v. Federal Energy Regulatory Commission on August 2, 2019. In a Per Curiam opinion, the court denied petitions challenging the Commission’s orders permitting the Transcontinental Gas Pipe Line Company’s expansion of an existing natural gas pipeline which extends from northern Pennsylvania across the Carolinas into Alabama. The expansion is called the “Atlantic Sunrise Project.” In February 2017, FERC approved the expansion, and denied various petitions, filed by environmental organizations and affected landowners, who then challenged the decision in the DC Circuit. However, the court concluded, on the basis of the administrative record, that these challenges “cannot surmount the deferential standards of agency review and binding DC Circuit precedent.” Under the law, the Commission must consider whether the projected pipeline project meets a market need, and whether the public benefits outweigh the harms. If both criteria are satisfied, FERC will, as in this instance, issue a certificate authorizing the pipeline’s construction, and that certificate also empowers the certificate holder to exercise eminent domain authority under to the Natural Gas Act when necessary. It was the latter consequence of the FERC’s determinations that caused several Pennsylvania landowners to file their objections with the Commission and seek to stay construction.
